Investigating polymer quantum mechanics : mathematical formulation, the particle on a ring, and time evolution

Creator:: Seibert, Basie S.
Abstract:: Loop quantum gravity is a theoretical framework which aims to quantize general relativity. One of the unique aspects of this theory is that it imposes a discrete structure on space-time. One toy model of loop quantum gravity is loop quantum cosmology, which maintains the idea of a discrete spatial structure...

The particle on a ring in polymer quantum mechanics : a quantum cosmology analogue on a compact space

Creator:: Siebersma, Maxwell R.
Abstract:: Loop quantum gravity is a framework for quantizing general relativity which imposes a discrete structure on space. In exploring the structure of loop quantum gravity, researchers have investigated loop quantum cosmology, a toy model with reduced degrees of freedom while maintaining a discrete space. Polymer quantum mechanics is a framework...

Locating and Observing Pulsars for Use in Gravitational Wave Detection

Creator:: Díaz, Ian H.
Abstract:: By studying gravitational waves, we can gain new insights into the merging events between massive objects such as black holes as well as neutron stars. Moreover, studying low-frequency waves allows us to observe merging events between supermassive black holes at the centers of galaxies, which in turn allows us to...

Analysis of Radio Signals for New Pulsar Detection

Creator:: Downing, Jaden
Abstract:: The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) times periodic signals from pulsars as a method of detecting gravitational waves. NANOGrav detects waves emitted in the nanohertz frequency range, a range lower than those previously explored by other organizations. This allows for the study of rarely observed sources such...

Regulation of Microtubule Dynamics by Engineered Kinesin-14 Motors

Creator:: Eagen, Emily
Abstract:: Microtubules (MT) are highly dynamic cylindrical-like structures within cells whose growth is controlled by motor proteins, a class of biological machines that walk along the MT while simultaneously regulating MT growth. Here we are interested in the behavior of kinesin-14 motor proteins. Although processive behavior of kinesin-14 motors has been...

Estimating basal glacier conditions using internal layer slopes

Creator:: Carroll, Georgia
Abstract:: Ice-penetrating radar produces detailed images of the internal ice layers in a glacier. Because the layers form from each year's snowfall, the curving of the internal layers is a record of the climate conditions that the glacier experienced as it flowed throughout the millennia. The Hiawatha Glacier lies on top...

Investigating Carrier Temperature in LED Quantum Well Driven Below the Turn-On Voltage

Creator:: Jeliazkova, Michelle
Abstract:: Electron behavior in semiconductor materials critically determines electronic applications. Previous research has shown carrier temperature higher than the lattice temperature of LEDs due to energy differences in the quantum well. Study of these findings requires a novel set-up to dig out weak signal in a thermal-noise filled environment; analytical methods...

Measuring Bubble Pressure in Glacier Ice

Creator:: Clonch, Cameron E.
Abstract:: Recent observations of tidewater glaciers find that the currently accepted model for predicting ice melt vastly underestimates observed melt rates. The release of pressurized air bubbles into the ocean from pores in the ice is one process that can amplify glacier melt. To incorporate this process into models, we need...

Twist in a Torus: Minimization of Nematic Conﬁgurations with Discontinuous Director Fields in Toroidal Coordinates

Creator:: Reid, Trevor S.
Abstract:: The ring disclination is a topological defect that may be suitable for light polarization inside of a nematic liquid crystal. Due to its stability and chirality, the ring disclination could also allow for theoretical applications to quantum and classical ﬁeld theories as a model for fundamental particles. In order to...

Cancer Cell Detection with Mask R-CNN

Creator:: Wong, Ryan
Abstract:: Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...

Isolating Non-Blackbody Radiation Spectra from Low-Bandgap LEDs near Zero Bias

Creator:: Teo, YiPeng
Abstract:: The study of carrier transport in light-emitting diode (LED) has been researched extensively in the past. However, most studies were implementing voltages above the turn-on voltage of the LED. Research on LEDs well below the turn-on voltage threshold is comparatively scarce for good reasons. When the supply voltage is below...

Searching for Pulsars for Use in Gravitational Wave Detection

Creator:: Connolly, Genevieve J.
Abstract:: Gravitational waves (GWs) are disturbances in spacetime that can be caused by events such as black hole mergers and supernovae, as well as continuous sources such as binary star systems. GWs offer a new avenue of astrophysical research and can reveal information about the early universe. GW detection can be...

Connecting computational thinking and mathematics: an examination of linguistic opportunities and challenges

Creator:: Glickman, Abbie A.
Abstract:: In this paper, I used a linguistic lens of translanguaging and semiotics to examine how K-12 mathematics teacher candidates (TCs) create meaning around computer science (CS) and mathematics concepts in a computational thinking (CT) setting. I defined the term “disciplinary repertoire” as a mirror to the concept of a linguistic...

Corrugation Instabilities Across Shock Fronts in Magnetohydrodynamical Astrophysical Systems

Creator:: Mullins, Austin Charles
Abstract:: Slow magnetosonic shock fronts are unstable to changes made to their shape, a phenomenon known as corrugation instability. The computational models studied considers a system where plasma travels across a shock front. Using the code Linogen, the corrugation instability of a shock front can be theoretically modeled. The results show...

Improving the Photostability and Recovery of Organic Semiconductors

Creator:: Tollefsen, Ryan J.
Abstract:: This work aims to broaden use of the organic semiconductor pentacene (Pn) by means of improving its oxidation and photodimerization stability. In particular, we study the photophysical properties of functionalized Pn derivatives with side groups R in amorphous thin film, referred to as Pn-R-F8 when fluorinated. Using the optics experiments...

Modeling the Fusion Reaction in an Inertial Electrostatic Confinement Reactor with the Particle-in-Cell Method

Creator:: van de Lindt, Jacob
Abstract:: Nuclear fusion has the potential to meet the energy needs of our civilization for centuries to come and does not produce harmful greenhouse gasses or produce long-lasting radioactive waste. A fusion reaction can be readily demonstrated in a confinement scheme known as inertial electrostatic confinement (IEC) fusion. In this work,...

Moral Truth and Hume's Fork: The Prospects of Reconciliation

Creator:: Embleton, Clark A.
Abstract:: Hume’s division of truth into agreement with matters of fact or relations of ideas casts doubt on our capacity to have moral knowledge, as moral propositions do not seem to fall obviously into either category. This thesis looks at how two views, ‘descriptive moral functionalism’ and ‘moral concept essentialism’, try...

Examination of the Impact of One-Dimensional Crustal Structures on Cascadia Subduction Zone Earthquake Locations

Creator:: Meyer, McKenzie S.
Abstract:: Multiple earthquake events have been recorded off the coast of Oregon, yet their locations have great uncertainty. The largest source of uncertainty is the simple models of the crust that are used to interpret seismic recordings. Because the relationship between earthquake locations and crust are diagnostic of tectonic activity, it...

Consistent Histories Formulation of the Double-Slit Experiment

Creator:: Bauml, Benjamin N.
Abstract:: The standard interpretation of quantum mechanics (known as the Copenhagen interpretation) divides the world into quantum phenomena and classical observers that perform measurements upon the phenomena. This provides a quite functional framework for calculating probabilities of measurement outcomes, but it lacks the generality necessary for such things as retrodiction, and...
